## Features

- 2 stage adjustable output pressure. The two-stage construction provides constant output pressure regardless of the amount of CO2 gas in the CO2 cylinder, so you can avoid unpredictable catastrophs like EOTD (Bottom of Tank Tipping) The output pressure can be adjusted from 0 to 65 PSI depending on your request
- Copper has outstanding conductivity compared to other metals. The regulator is made of pure copper instead of traditional aluminum
- Block Design Includes 2 manifold blocks. Each block is equipped with a precision needle valve that allows it to work independently. One tank uses one block Two aquariums can be used with two blocks
- The solenoid valve works with DC 12V instead of conventional AC 12V. This regulator adapts to DC12V to ensure more stable operation and low power consumption. The solenoid is safe to the touch and very quiet. This solenoid is designed to work with timers
- Safety and Precision Our regulators have a built-in safety valve. Automatically opens when pressure exceeds 100PSI. The built-in needle valve is a precision part. The CO2 output can be adjusted up to 1 bubble in 3 seconds

## Questions & Answers

**Q: The needle valve isn't very good. The bubble count drifts often. Is there a way to manage this? Or change out for a better needle valve?**
A: I don’t have that problem with either of mine.   The needle valve is a secondary regulation device.  Try adjusting the primary regulator valve down. This will reduce pressure to the needle valve.

**Q: I just set up the regulator. But i see that even with the power off, bubbles are coming out of the bubble counter. Is this normal?**
A: No. That is not normal. The solenoid should shut off the flow completely. However, make sure you do not have the regulator pressure set too high. The regulator should be set to the lowest pressure that will allow bubbles to flow. Mine runs a little over 20 psi. If the pressure is set to high, the solenoid might leak.

**Q: what size wrench do i need to tighten this regulator onto the bottle of co2?**
A: I just use an adjustable monkey wrench on mine. You don’t have to tighten it incredibly tight.

**Q: would I need a stand-alone check valve when using this regulator with an inline diffuser?**
A: The manufacturer says the bubble counter has an integrated check valve. So no. But I would!
